THE ICE AGE?....

BY KEVIN SARAVIA AND CHAD SEVERT

WHEN WAS THE LAST ICE AGE?..

The last glacial period was the most recent glacial period within the current ice age occurring during the last years of the Pleistocene, from approximately 110,000 to 10,000 years ago.

During this period there were several changes between glacier advance and retreat. The maximum extent of glaciation was approximately 22,000 years ago. While the general pattern of global cooling and glacier advance was similar, local differences in the development of glacier advance and retreat makes it difficult to compare the details from continent to continent (see picture of ice core data below for differences).

WHAT CAUSED THE ICE AGE

Climate on Earth has changed on all time scales, including

long before human activity could have played a role. Great progress has been made in understanding the causes and mechanisms

of these climate changes. Changes in Earth’s radiation balance

were the principal driver of past climate changes, but the causes

of such changes are varied. For each case – be it the Ice Ages, the

warmth at the time of the dinosaurs or the fluctuations of the past

millennium – the specific causes must be established individually.

In many cases, this can now be done with good confidence, and

many past climate changes can be reproduced with quantitative

models.

how the earth overall changed?..


The impact of increased surface temperatures is significant in itself. But global warming will have additional, far-reaching effects on the planet. Warming modifies rainfall patterns, amplifies coastal erosion, lengthens the growing season in some regions, melts ice caps and glaciers, and alters the ranges of some infectious diseases. Some of these changes are already occurring

ice age organisms that went extinct

there were many intersting mammals dureing the ice age, but saddley many went extinct. Like the saber-toothed cats and the giant ground sloths. Mastodons and mammoths all went exctinct. Many animales we have today have adapted to warmer waeather such as bears, deer, and many others. all these animales use to live in cold waether. then moved closer to the pleistocene.

did a astronomical event start the ice age?

The astronomical theroy is the theroy that astronomical called crazy changes in climate witch could of caused ice ages.
